Tape casting, also known as belt casting method and doctor blade method, is an important molding process for thin ceramic materials. The process was first used by GN. Howatt is used in the field of ceramic forming and has been used in the production of single-layer or multi-layer thin-sheet ceramic materials since it was patented in 1952. The tape casting molding equipment is relatively simple, the process is stable, the continuous operation is possible, the production automation is convenient, and the production efficiency is high. The disadvantage of tape casting is that the binder content is high, so the shrinkage rate is large (up to 20%). At present, this process Read more

Zirconia ceramic spool is a better spool, which has the characteristics of strong wear resistance and good sealing performance. The heart of the faucet is its valve core. To choose a good faucet, you must first understand the valve core of the faucet. Now the common valve cores mainly include: stainless steel valve core, copper valve core and ceramic valve core. The stainless steel valve core is a kind of faucet valve core with high technology content at present, but if the stainless steel material is not qualified, it is easy to rust and pollute the water quality. The copper spool is the heaviest and most expensive spool. It also Read more

Pintejin Ceramics Factory is a manufacturer specializing in the production of structural ceramic parts. Structural ceramics are a type of fine ceramics. This type of ceramic has a series of advantages such as high temperature resistance, corrosion resistance, wear resistance, erosion resistance, etc. The following is a brief analysis of structural ceramics by Pintejin ceramics. Classification of structural ceramics for structural alumina ceramic tubes: There are many types of structural ceramics, which are classified into the following series according to raw materials: Oxide ceramics, mainly including alumina ceramics, zirconia ceramics, mullite ceramics, etc.; Carbide ceramics, mainly including silicon carbide ceramics, titanium carbide ceramics, boron carbide ceramics, etc.; Boride ceramics, There Read more

Zirconia ceramic plastic clay mass is a plastic-viscous system composed of solid phase, liquid phase and gas phase, and is composed of powder, binder, plasticizer and solvent. The important difference between zirconia ceramic plastic clay mass and slurry is the difference in solid-liquid ratio. The water content of zirconia ceramic plastic mud is generally 19% to 26%, while the water content of the slurry is as high as 30% to 35%. There are two forces between the particles of the mud mass: Suction, mainly van der Waals force, electrostatic attraction and capillary force. The suction range is about 2nm. The capillary force is the main source of the gravitational force Read more

With the development of my country’s economy and the change of consumption consciousness, traditional industries have also entered the fast lane of development. For zirconia ceramic enterprises participating in the fierce market competition, the brand is not a fashion or avant-garde theory, but a practical and effective tactic. What is needed is to let customers finally become users and sharers of products and services among many choices. and communicators. Therefore, zirconia ceramic enterprises need to do a good job of zirconia ceramic brand building strategy in order to truly stabilize their market position. 1. Why zirconia ceramic enterprises should build brands Abandoning academic concepts and introducing popular language, in short, Read more

The shaft is supported by zirconia ceramic bearings, and the shaft segment matched with the bearing is called the journal. The journal is the assembly benchmark of the shaft, and their accuracy and surface quality are generally required to be high. The technical requirements are generally formulated according to the main function and working conditions of the shaft, and usually include the following items: (1) Dimensional accuracy of zirconia ceramic bearings In order to determine the position of the shaft, the journal of the zirconia ceramic bearing that supports the bearing usually requires high dimensional accuracy (IT5~IT7). The dimensional accuracy of the journal for assembling transmission parts is generally low Read more

Pintejin Ceramics is a professional manufacturer of zirconia ceramics. Do you know enough about zirconia ceramics? The following is a detailed introduction of zirconia ceramics by Pintejin ceramic manufacturers. Zirconia Ceramic Sheet Pure zirconia ceramic is white, yellow or gray when it contains impurities, and generally contains HfO2, which is not easy to separate. The world’s proven zirconium resources are about 19 million tons, and zirconia is usually obtained by purifying zirconium ore. There are three crystal states of pure ZrO2 under normal pressure: monoclinic (Monoclinic) zirconia (m-ZrO2), tetragonal (Tetragonal) zirconia (t-ZrO2) and cubic (Cubic) zirconia (c-ZrO2). The production of zirconia ceramics requires the preparation of powders with high purity, Read more

There are many methods for surface metallization of industrial ceramic substrates. The co-firing method is introduced above. Through high temperature or low temperature co-firing, the performance of zirconia ceramics and alumina ceramic substrates is enhanced and more beautiful. Next, Pintejin Ceramics will continue to introduce the surface metallization of thick film method. The thick film method refers to the production process in which the conductive paste is directly coated on the ceramic substrate by screen printing, and then sintered at high temperature to make the metal layer firmly attached to the ceramic substrate. The choice of thick film conductor paste is a key factor in determining the thick film process, Read more

Silicon carbide ceramics are non-oxide ceramic materials without any metal elements. They are composed of carbon and silicon elements. They have a particle structure similar to diamond, so they are high-strength, hardness and high-temperature corrosion-resistant ceramics. Industrial ceramics are also the most widely used ceramics among non-oxide ceramics. Silicon carbide ceramics have different properties and different application fields due to their different preparation processes, but they are mainly used as high-temperature structural materials, refractory materials, and wear-resistant mechanical seals by using their high temperature resistance, wear resistance, corrosion resistance and other characteristics. materials, acid and alkali-resistant corrosion-resistant materials and high-temperature heat exchange materials, etc. Silicon carbide ceramics can be divided Read more

Zirconia ceramic structural parts can be metallized through some processes. The following Pintejin Ceramics Factory will take you to understand this technology. The metal of the zirconia ceramic structure is melted, and the cross section begins to be filled with its F form, and the fusion of its F4FH weld is carried out through the metal section, and the fusion ratio is 7. When its size affects welding, the composition and the mechanical properties of the product combination can be compared, and the proportion of the weld of the entire metal is a part of the size, so when the steel of the weld is compared with the chemical difference, Read more
